Description

Technical Field

[0001] This utility model belongs to the field of battery recycling technology, and in particular relates to a desulfurization device for lead paste from waste lead-acid batteries. Background Technology

[0002] Waste lead-acid batteries contain a large amount of heavy metals, and direct disposal will cause serious environmental pollution. Therefore, the internal materials need to be processed and recycled. During the recycling process, the lead paste contained in waste lead-acid batteries contains sulfur compounds. These sulfur compounds react with other solvents in the equipment during the recycling process, producing toxic sulfur-containing gases that pose a health risk to workers. Therefore, an alkaline solution needs to be added to the container containing the lead paste for desulfurization. This method requires continuously adding and mixing the lead paste and alkaline solution from the waste lead-acid batteries, making the desulfurization process inefficient and unsuitable for processing large quantities of lead paste. Furthermore, the increased moisture content of the lead paste after mixing with the alkaline solution is detrimental to subsequent recycling processes.

[0003] To address these issues, we provide a waste lead-acid battery lead paste desulfurization device. Utility Model Content

Lead paste recovered from waste lead-acid batteries is poured into the conveyor cylinder through the feed pipe. The screw conveyor pushes the lead paste forward in a spiral motion, and the spray assembly sprays an alkaline solution into the conveyor cylinder. The alkaline solution mixes with the lead paste as the screw conveyor rotates and pushes it forward, thus desulfurizing it. A drying assembly is installed at the output end of the conveyor cylinder to dry the lead paste conveyed from the conveyor cylinder, allowing the desulfurized lead paste to be discharged after drying.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] Please see Figures 1 to 2This utility model relates to a desulfurization device for lead paste from waste lead-acid batteries, comprising a conveying assembly 1, a spraying assembly 2, and a drying assembly 3. The conveying assembly 1 includes a conveying cylinder 101 and an auger pusher screw 102. The auger pusher screw 102 is rotatably installed in the conveying cylinder 101. A feed pipe 101b is installed on the upper side of one end of the conveying cylinder 101, and the spraying assembly 2 is installed above the conveying cylinder 101. The lead paste recovered from the waste lead-acid batteries is poured into the conveying cylinder 1 through the feed pipe 101b. The auger pusher screw 102 pushes the lead paste forward in a spiral motion, and the spraying assembly 2 sprays an alkaline solution into the conveying cylinder 101. The alkaline solution and the lead paste are pushed forward by the rotation of the auger pusher screw 102 and mixed for desulfurization. The drying assembly 3 is installed at the output end of the conveying cylinder 101 to dry the lead paste conveyed from the conveying cylinder 101, so that the desulfurized lead paste is discharged after drying.

[0027] Specifically, the conveyor cylinder 101 is placed horizontally with openings at both ends. One end of the conveyor cylinder 101 is fixedly fitted with a cylinder end cap 101a. The spray assembly 2 is fixedly installed on the upper pipe surface of the conveyor cylinder 101. The drying assembly 3 is installed on the end of the conveyor cylinder 101 away from the cylinder end cap 101a. An opening is opened on the upper pipe wall of the end of the conveyor cylinder 101 near the cylinder end cap 101a, and a feed pipe 101b is connected above the opening. One end of the auger pusher screw 102 is rotatably installed on the plate surface of the cylinder end cap 101a and passes through the cylinder end cap 101a. The shaft end of the auger pusher screw 102 passing through the cylinder end cap 101a is connected to the output shaft of the motor through a sleeve belt. The end of the auger pusher screw 102 away from the cylinder end cap 101a is rotatably installed in the drying assembly 3.

[0028] Furthermore, the spray assembly 2 includes an isolation cover 201 and a set of spray pipes 202. A receiving cylinder 101c is fixed at one end of the conveying cylinder 101 away from the feed pipe 101b. The receiving cylinder 101c is a semi-cylindrical shape with its opening facing upward. A semi-cylindrical basket 201a with its opening facing downward is fixed at the lower end of the isolation cover 201. The semi-cylindrical basket 201a is sleeved on the upper end of the receiving cylinder 101c. The spray pipes 202 are fixedly installed on the upper end of the isolation cover 201. A set of spray heads 202a is installed at the lower end of the spray pipes 202. The spray heads 202a spray an alkaline solution into the isolation cover 201. The alkaline solution passes through the semi-cylindrical basket 201a and enters the conveying cylinder 101 to mix with the lead paste.

[0029] The operation process in this embodiment is as follows:

[0030] Lead paste recovered from waste lead-acid batteries is poured into conveyor cylinder 101 through feed pipe 101b. The auger pusher screw 102 rotates, causing the lead paste in conveyor cylinder 101 to spiral forward. Spray head 202a sprays alkaline solution into isolation cover 201. The alkaline solution passes through semi-cylindrical basket 201a and enters conveyor cylinder 101. Under the rotation of auger pusher screw 102, the alkaline solution mixes with the lead paste, desulfurizing the lead paste. Example 2

[0031] Please see Figures 1 to 5 Based on Example 1, the drying assembly 3 includes a transparent sleeve 301, two lamp rings 302, a set of electric heating lamps 303, and a discharge conveyor 304. The heat emitted by the electric heating lamps 303 dries the lead paste inside the transparent sleeve 301, thereby drying the lead paste mixed with the alkaline solution.

[0032] Specifically, the two ends of the transparent sleeve 301 are connected to the end cap 101a away from the conveying cylinder 101 and the discharge conveying cylinder 304 through flanges, respectively. The auger pusher screw 102 is sleeved inside the transparent sleeve 301 and the discharge conveying cylinder 304. Two lamp tube rings 302 are fixedly sleeved on the outer walls of the two ends of the transparent sleeve 301, respectively. The electric heating lamp tubes 303 are arranged in a circumferential array between the two lamp tube rings 302. The lower side wall of the discharge conveying cylinder 304 away from the transparent sleeve 301 has an opening and the discharge pipe 304a is connected inside the opening.

[0033] Furthermore, a reflector 302a is fixedly sleeved on the outside of the two lamp tube rings 302. The inner wall of the reflector 302a is a mirror layer, so that the heat emitted by the electric heating lamp tube 303 is reflected into the transparent sleeve 301.

[0034] Furthermore, a ventilated end cover 304b is fixedly connected to the end of the discharge conveyor cylinder 304 away from the transparent sleeve 301. The shaft of the end of the auger pusher screw 102 away from the cylinder end cover 101a is rotatably mounted on the ventilated end cover 304b. A set of ventilated holes 304b-1 are opened on the cover surface of the ventilated end cover 304b. A set of ventilated holes 102a are circumferentially arrayed on the blades of the auger pusher screw 102. The ventilated holes 102a are parallel to the axis of the auger pusher screw 102, so that the airflow in the transparent sleeve 301 can communicate with the outside through the ventilated end cover 304b. The ventilated holes 102a further connect the blades of the auger pusher screw 102 with the outside, so as to facilitate the discharge of the heated humid air in the transparent sleeve 301.

[0035] Furthermore, an exhaust fan 304b-2 is installed on the end plate of the vent end cover 304b away from the transparent sleeve 301. The exhaust fan 304b-2 accelerates the gas flow inside the transparent sleeve 301, thereby accelerating the drying of the lead paste.

[0036] Furthermore, brackets 4 are fixedly installed on the lower side of the conveyor cylinder 101 and the lower side of the discharge conveyor cylinder 304, respectively, to support the conveyor cylinder 101 and the discharge conveyor cylinder 304.

[0037] The operation process in this embodiment is as follows:

[0038] After being desulfurized by spraying alkaline solution, the lead paste enters the transparent sleeve 301 under the push of the auger screw 102. The electric heating lamp 303 generates heat to heat and dry the lead paste in the transparent sleeve 301, causing the moisture in the lead paste to evaporate. Under the action of the exhaust fan 304b-1, it is discharged from the vent hole 304b-1 on the vent end cover 304b. After drying, the lead paste falls from the discharge pipe 304a under the push of the auger screw 102 to complete the discharge.
